Control method for carbonization system in biomass external thermal method thermal carbon co-production system

Abstract

The invention relates to a control method for a carbonization system of a biomass external thermal method thermal carbon co-production system, wherein the carbonization system comprises a feeding mechanism, a material preparing mechanism, a carbonization reactor, a gas discharge pipeline a, a gas discharge pipeline b and a material collecting mechanism, the residence time of a material in the carbonization reactor is determined by the average particle size and the water content of the material, and the correlation is described by the following equation: t=a*m*e<d / m>+b, wherein t represents the residence time of the material in the reactor, a represents a material particle size correlation constant and is 52.131, b represents a material water content correlation constant and is 15.260, e represents a natural constant and is 2.718, d represents a material average particle size, is more than or equal to 0.003 and is less than or equal to 0.05, and has the unit of m, and m represents a material dry group water content, and is more than or equal to 5% and is less than or equal to 80%. According to the present invention, by controlling the residence time of the material in the carbonization system, the carbonization degree of the material can be controlled efficiently, the heating is performed for the optimal time, the minimal heat energy is consumed, the optimal carbonization effect is generated, the carbonization efficiency ratio is optimal, and the conveniently-used environmentally friendly flue gas is produced so as to improve the carbonization efficiency of the material.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of agricultural biomass waste, and specifically relates to a control method for a carbonization system in a thermal carbon cogeneration system of a biomass external heat method. Background technique [0002] In recent years, my country's agriculture has continued to develop steadily, and the level of large-scale farming has been significantly improved, ensuring the supply of meat, eggs and milk. However, a large amount of agricultural waste has not been effectively treated and utilized, which has become a major problem in rural environmental governance. Doing a good job in the resource utilization of agricultural waste is related to the effective supply of agricultural products and the improvement of the production and living environment of rural residents. It is a major livelihood project. [0003] At present, the market mainly uses biogas engineering and composting for the reso...
